f invention `relates generally to lattach- .ments for paint `brushes and other scribing instruments, and an important object olf-my invention is to provide an attachment which will act as. a guide in painting-or otherwise working .upon confined areas of surfaces, whereby the effect ofthe work may berestricted to the .confined areas.

A it is also an important tion to provide a device of thecharacter described, whereby kItis also an important object of my invention to provide ya simple and easy to manufacture attachment scribed, which may be "easily applied to the paint brush or the like, and which may be easily and quickly attached o-r detached.

Other objects-and advantages of my iny vention willbe apparent from a reading of` the following description in connection withy the drawing, wherein for purposes of illustration I have shown a preferred embodiment of my invention. y Y z In the drawing z- Figure 1 is an end elevational view of a paint brush showing attached thereto an embodiment of the invention.. l j

Fioure 2 is an end elevational view taken `from the left of Figure'l.V p

Figure 3 is a top plan view-of the embodiment perse. t

Referring.` in detail fto the drawing, wherein like numerals refer to like` parts throughout the same, thenumeral 5 generally .designates a paint brush or the like having the bristle holding portion Y6 and the bristles 7. The device of the invention hasaportion to clamp upon the bristle holdingv brush 6 forV securely but detachably connecting" the -deanother portion of the device surrounds and confines a portion of the bristles 7 while another portion of the device may be placed against the surface to be acted upon or any structure adj acentto and forming a boundary of the confined surface which is to be yworked upon, whereby the brush 5 when manipulated` will vwork only upon such confined area.

object of my inven- Y the effort and skill usuallyy vby ` of the character l de- Y the brush so thatv .l The attachment per f or other suitable material be bent into the general U-shaped form shown se comprises a metallicir y plate 8 vwhich may in F igureB to provideopposedspaced sides v 9," 10l and an interposed generally curvedV portion As seen in haveA a edge thereof. A portion of what will designated as the lower is cut away as indicated at 13 so thatthere 1s f defined partsl of the sides and parts of the rweb 11.

11. Figure 1 thev-sidesU9-and 10y slot 12 :cut inwardly` from the outer be end of the sides 9,1() 'CJ a pointed portionM which is defined It will be observed that the web 11v has been bristle brushes ons that the portion 11 might be made rectanj t f f shown as curved in form merely because thev G5 yholdingy Aportions 6 `of mosty paint have'k curved ends. It'will be obvi- 'r gular in form or in any other` suitable form to enable portion portion ment is a properly snug engagement of their7 11 with the end of the brush holding 6 of any. brush to which the attachy to be connected.

It will be observed that the notch 12 is i laced so that a sufficient portion of the sides*` 75 9, 10 will be above the bristles 7 for securely and frictionally engaging thesides ofthe brush holding portion ing will result between 6 and a suliicient spacthe bristle holder portion engaging part 16 of the sides 9, 1()` and '80 the bristle confining part 16 of the sides 9, 10 which should be sufficiently wide for enclosing one side of the bristles 7 of the paint brush or .the like. It will be obvious that the transverse dimension of the bristle Aholding portion 6 of the brush greater bristles being in some instances transverse dimension of the of the slot 12 enables than the 7*, the provision easily bending the brush confining parts 16 of the sides 9, 10 toward each other oraway` from each otherv to accommodate the transverse dimension of the bristles 7 turbing As already intimated the parts ranged without disthe gripping action of thev parts-'15.

ing them 'upon the brush or the'like and they y havel suiiicient resilience to grip the sides of the` bristle holding portion 6 in the manner shown.v

1n at taching the attachment to the brush, lo@

the loWer end of the pointed portion 14 is disposed on a level With the free ends of the bristles 7. Thepointed portion 14 or the back of the portion 11 is placed against any guiding element bounding the surface to be Worked upon, so that a sliding bearing is effected betvveen'these portions and theguiding element for restricting the lrnovementof the brush bristles. For instance, inq'aainti-ng a Window frame, the point 14 Would be engaged over'and againsttlie inner edge ofthe Window frame and possibly engage the glass While the brush Would be reciprocated across the frame so as to paint lengthwise of one side thereof, and duringl this movement the bristles would be confined exactly to the side of the Window frame land lnot permitted to paint any portionof the glass inthe Window frame. fn the event of painting a Hoor close to baseboard or Wall,'the back of the portion 11 of the attachment would be made to slide along the balseboard or Wall, and the baseboard or Wall would 'be protected against ybeing painted by the bristles 7 The formation. ofthe cutl ont 'portion A13 ris such as to lmake available the full breadth of the brush orthe like,and yet'confine thevbristles thereof in the manner mentioned. rllhisenables full use of the brush but .prevents inaccurate mainipulation thereof.

Though Iliiave sho-Wn and described herein lfa preferred embodiment vof'my invention', lit

portion embracing Vingto. the 'ends of 'thesfpaint brush.

is to be definitely understood that I do not desire to limit the application of the invention thereto, and any change or changes may be made in material and structure and arrangement of parts, Within the spirit of the invention and the scope of the snbjoined claims.

What is claimed is t` 1. The combination portion and bristles extending therefrom, of a body for einbrac-l ing 'and confining a portion of the bristles, said body including a portion detachably enibracing 'the' 'bristle holding portion for removably mounting he body on the paint brush, said body being located at one side of :thepaintbrush and having a lportion extending to ythe ends of the bristles whereby toprevent spread of the bristles beyond the last mentionediportion.

. 2. An attachment for a paint brush having a bristle holding portion and bristles'cxtending therefrom, said attachment comprising a plate bent to -provide tension members for receiving and l'embracing a portion of the V bristleholding portion `for detachably mount-- ing the attachment an deonfining Athe bristles, an extension on the last named :portion reachthebristles at one side of In testimony Whereof'l aliiriimy. signature.
